Answer:
<em>0.47</em>
Explanation:
The Growth/decay factor is a factor that determines how fast a process increase or decreases.
<h3>Calculations</h3>
Given 10 hrs decay/growth factor = 0.2213
5 hrs decay/growth factor x=?
To obtain the 5 hours decay/growth factor we have to obtain 1-hour decay/growth factor;
let x be the 1-hour growth/decay factor and we have the expression below;


x = 0.86
The one-hour growth/decay factor is 0.86
Now the 5-hours growth/decay will be;


5 hours growth/decay factor = 0.47
<em>Therefore, the five-hours growth/decay factor for the number of mg of caffeine in Juwan's body is </em><em>0.47</em>
